(54) | Manufacture of sanitary ware |
(57) An article of sanitary ware such as a shower tray 1 having a composite construction,
includes an outer skin 20 of plastics material forming an upper surface of the tray,
a backing layer 21 of resin concrete applied to the underside of the skin, and a partial
back skin 22 covering less than 90% of the underside of the backing layer. The remainder
of the underside is uncovered to allow removal of air from the resin concrete during
manufacture. A number of inserts are cast into the backing layer to form sockets into
which support elements may be inserted to support the article above a surface on which
it is installed. The sockets are bolted to a carrier tool in sealing contact with
the partial back skin which is held between the sockets and the tool. The manufacturing
process can be carried out without using release agents or high pressure moulding.
